A space for simulation related technical resources and discussions.
Power supplies are the backbone of the electrified world. Converter requirements, advancements in switches, magnetics, topologies, and control techniques require you to have a dynamic, fast, accurate, and purpose-built simulation tool for power electronics. Powersim has been providing simulation tools for power supplies…

Modelling a TVS with PSIM A uni-direction TVS can be modelled with a zener diode. A bi-directional TVS can be modelled with two zener diodes, connected cathode to cathode From Littlefuse Breakdown Resistance We can calculate the resistance of the device by using the breakdown voltage and current to calculate the slope of…
A three-point bending flexural test is a standard test in which a specimen is loaded under uniaxial bending stress. The test is performed to obtain material properties such as elastic modulus in bending, stress-strain behavior, and failure limits. Some standards are used for this test. For example, ASTM D790 or ISO 178 are…
Constraint lines in S-FRAME Analysis provide an efficient method for defining connections between panels and walls. Part 2 of this webinar series* explains how and why you should use the Constraint Line tool in S-FRAME Analysis. Watch to learn about: * Rigid Constraint Lines – used to connect shell elements that may not…
Extracting Design Forces using Wall and Strip Integration Lines in S-FRAME Wall Integration Lines, Strip Integration Lines, and Constraint Lines: what are the benefits and how are they used? Integration and Constraint lines are efficient tools when analyzing and designing walls and slabs. This two-part webinar series…
We are often asked how to represent steel decks in S-FRAME and wanted to provide a road map for those looking to do just that. Assume we have a steel deck that we wish to analyze in S-FRAME. It is important to use accurate material properties to represent the stiffness of the steel deck. We can work with the information…
This article gives more information regarding the concept of ports and sources in CADFEKO. What is a port in CADFEKO To cause current to flow in a model, you need to excite or illuminate a model. A port is a mathematical representation of where energy can enter (source) or leave a model (sink). Define a port where you want…
Abstract In this article we will use a novel AI-based application, romAITM, to generate a Reduced-Order-Model (ROM) from a large database of static simulations and optimize their parameters. We will demonstrate how this innovative approach can support the design of an Aircraft Wing. The romAI model will be used to estimate…
